- Troubleshooting machine if things go wrong

examples: 
1. - Problem: Seeing random layer lines on part
   - Cause: Loose Belts
   - Solution: Tighten belts till pricking them gives them a slight twang.

2. Problem: Stepper motor suddenly very noisy or skipping steps
   - Cause: Loose cable ends in JST connectors going to stepper driver ports on controller board 
   - Solution: Make sure all four wires from stepper motor are properly inserted into the JST connectors

3. Problem: First layer not sticking to bed
   - Cause 1 : Dirty bed (grease, fingerprints, dust etc.)
   - Solution: Clean bed with isopropyl alcohol and dry

   - Cause 2: Z-Offset not set right i.e. Zero Nozzle position too far away from bed i.e. at the Z=0 position there is a gap between nozzle and bed.
